: 创建名称为 'expressionHandler' 的 bean 时出错

Question

我在使用 spring acl 时遇到错误，我只是将一些 class 范围更改为自定义范围并且在部署应用程序时我遇到了错误 : 创建名称为 'expressionHandler'

的 bean 时出错

全栈：

bean初始化失败；嵌套异常是 org.springframework.beans.factory.BeanCreationException：创建名称为 'expressionHandler' 的 bean 在 class 路径资源 [spring-security-acl.xml] 中定义时出错：无法解析对 bean 的引用 'permissionEvaluator' 同时设置 bean 属性 'permissionEvaluator';嵌套异常是 org.springframework.beans.factory.BeanCreationException：创建名称为 'permissionEvaluator' 的 bean 在 class 路径资源 [spring-security-acl.xml] 中定义时出错：无法解析对 bean 的引用 'aclService' 同时设置构造函数参数；嵌套异常是 org.springframework.beans.factory.UnsatisfiedDependencyException：在 class 路径资源 [spring-security-acl.xml] 中定义名称 'aclService' 创建 bean 时出错：通过构造函数参数表达的依赖关系不满足索引 1 类型 [org.springframework.security.acls.jdbc.LookupStrategy]：无法将类型 [org.jboss.jca.adapters.jdbc.WrapperDataSource] 的构造函数参数值转换为所需类型 [org.springframework.security.acls.jdbc.LookupStrategy]：无法转换类型 'org.jboss.jca.adapters.jdbc.WrapperDataSource' 的值到所需的类型 'org.springframework.security.acls.jdbc.LookupStrategy'；嵌套异常是 java.lang.IllegalStateException：无法将类型 [org.jboss.jca.adapters.jdbc.WrapperDataSource] 的值转换为所需类型 [org.springframework.security.acls.jdbc.LookupStrategy]：未找到匹配的编辑器或转换策略

感谢任何帮助。谢谢

问题出在创建租户对象时，我根据名称关键字将它放在地图中，并且由于一直使用相同的名称，我得到一种类型的对象，我通过区分地图键解决了它

public class TenantScope implements Scope {

Map <String,Object> map=new HashMap<String, Object>();
@Override
public Object get(String name, ObjectFactory<?> objectFactory) {
    // TODO Auto-generated method stub
    String tenantIdentifier = TenantThreadLocal.tenantThreadLocal.get()==null?"":TenantThreadLocal.tenantThreadLocal.get();
    System.out.println("tenantIdentifier in scope :"+tenantIdentifier);
    Object object=map.get(tenantIdentifier+name);

    if(object==null){
        object = objectFactory.getObject();
        System.out.println("object :"+object);

        map.put(tenantIdentifier+name, object);
    }
    System.out.println("returning object :"+object);
    return object;
}

@Override
public Object remove(String name) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public void registerDestructionCallback(String name, Runnable callback) {
    // TODO Auto-generated method stub

}

@Override
public Object resolveContextualObject(String key) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public String getConversationId() {
    // TODO Auto-generated method stub
    return null;
}

}
